To all iohom it may concern: .Be it known that I,Jorn-: Assonr SMlTH, acitizen I "of the United States, residing at Harrisburg, in the-'countyof Dauphin and State of Pennsylvania, have invented anew anduseful Automatic Key-Connecting Means for Combined Type-Writing andAdding Ma.

chines, of which the following is aspecification.

.This invention relates to combined typewriting and adding machines, andmore particularly to improved mechanism which will allow theunrestricted independent use i of the typewriter, but which, whenproperly set, willcause the keys of the typewriter to beautomaticallyconnected to the adding mechanism for the actuationthereof'when the printing point of the machine is presented opposite theadding field, and to be automatically disconnected when the movement ofthecarriage presents the printing point outside of said Mechanismadapted to effect the automatic connection and disconnection o'f;thekeys in the mann er stated has been heretofore devised, but suchmechanism has been comparatively complicated in character and more orless difiicult of instalment and repair.

Therefore, the primary object ol the invention is to provid a mechanismoithis character which will be extremely simple in. construction, easyof. instalment,

- adjustment and repair, and positive in action.

A further object of the invention is to associate with the automatic keyconnecting mechanism an indicator which, instead of indicating theconnected or discon-' nected condition of the keys, will indicatewhether or not the mechanism is set for automatic actuation, andconsequently whether ornot the keys will be auto- 'matically connectedWhen the adding field is reached.

Subordinate objects will'appear hereinaftcr as the description of theillustrated structure proceeds.

In the accompanying drawings-Figured is see 'tional elevationoi anElliott-Fisher billing machine equipped with automatic key connectingmechanisnr constructed in accordance'with my invention. Fig.2

Fig. 10 is a plan view of the indicator. Fig. 1].is a section on the line 11--1l of Fig. 4. Fig. 12 is a sectionalelevation, showing the positions assumed by the parts when the keys aredisconnected, and the mechanism is unset, the operated position of theintermediate lever being indicated in dotted lines. Fig. i3 is a similarview observed from the opposite side and with the mechanism in setcondition and the parts in the positiops they assume when operated tocause the connection of the keys. Fig. 14 is a detail sectional view ontheline 14-14 of Fig. 13, and Figs. 15 and 16 are detail perspectiveviews of the parts 46 and 53. Each part is indicated by the samereference character wherever shown.

The billing machinn 'lhe machine to which my invention is shown appliedis the Elliott-Fisher billing machine of commerce. This machine includesa flat platen 1 over which a machine frame 2 is mounted to travellongitudinally to space the lines of writing. Mounted to travel on theframe 2 transversely of the upper portion of which is in the form of acasing 4 'surmounted by letter and numeral keys 5 and 6, the stems 7 ofwhich are connected tokey levers 8 fulcrumed in the casing and connectedby draw-Wires 9 to downwardly swinging type bars 10. The carriage ismoved to the right by carriage propelling mechanism including springdrums, not shown, and tapes 11, a portion of one of the latter beingshown in Fig. 2. The letter spacing movement oi the carriage iscontrolled by keyopcratcd escapcment mechanism, indicated generally at12 in Fig. 1. As usual in this class of machines, the characters areprinted one at a time by the depression of the keys, and the.--.u'rizigc advances step-bystep under the. control of the esca'pomentas the keys rise.

The comp [thing in cclum'ism..--'lhis mechanism includes a computingdevice or register 13 adjustable longitudinally of a guidcbar 14 carriedby brackets 15 secured to the framoZ. The adjustment of the register 13enables the same to be located in position for use with reference.

to a columnlocatcd at any desired point on the work sheen which latteris supported in a Hat sprcadout K101i.- dition on the platen l.

The computing device or register usually embraces a series ofdc'nominatioual members or digit carriers disposed at the front of theregister and equipped with suitable carrying mechanism whereby, when thevalue accumulated upon any member reaches the limit of that particularorder or denomination, the value so accumulated will be automaticallytransferred to the wheel of next higher order. The primaryclement of theactuating mechanism forthe denominational mombers of the register is amaster wheel .16 mounted. on the platen to letter space the writingis acarriage 3, the

earriage I, of the typewriter and movable therewith into engagement withsueeessive denoutinatitmal memmember of eorrespomling denomination willbe given a movement; eorrespomling in value to that of the printeddigit, so that the. value of su'eh digit will be added to the amount;already :u'eutnulated in the register. master wheel ltS is tixed to aeomparatively long aetuator shaft 17 suitably supported above theearriage easing 4 and eaeh numeral key 5 is arranged to be operativelyeonneeted with the shaft by one of a series of operating eonneetiousident ieal in eonstruetion aud operat ion, exeept as to a graduatedvariation of the movement transmitted to the shaft from the severalkeys. ()ne of these operating eonneet ions is shown in Fig. l.

lt ineludes a ratehel wheel 18 tixed to the shalt l7 and designed to beengaged by a driving pawl It) earried at one eml of a driving arm orlever 30 mounted to swing loosely on the shaft l7. The opposite end ofthe levirr 21) is geared to the rear end of a lever 2| t'ulerumed at itsfront end on the earriage easing and arranged in erossing relation witha. lever 22 tulerumed at its rear end and having loose pivotaleonneetion with the lever 21 at the point of intm'seetiou of saidlexeis, as indieated at 2ft. From the front end of eaeh lever 22 dependsa link 24 eonneeted to the adjaeent numeral key stem 7 by a separableeonueetion 25 loeated within the easing 4. ln printing outside of aeolumn or adding held, the art uator or wheel H3 is out of eoineideneewiththe register l3, and therefore the latter is not operatedwh n adigit is priat d. H the eonneetion between the links 24 and the numeralkeys 5 were maintained, however,

the keys when printing digits outside of an adding lield would beburdened by the operating meehanisln oi the register, whieh meehanismwould neeessarily be operated upon eaeh depression of a key. Thisunia-eessary hardening of the numeral keys when printing outside of aeoiumn is undesirable, and furtln-rmore, it is desirable under someeireumstanees td print digits in what would otherwise be the adding heldwithout operating the register, as for instanee, in printing sub-totalsor a total. It is forthis reason that the links 24 are arranged t beswung out. of engagement with the numeral keys so as to render thelatter entirely independent of the register or its operatingeonneetions.

For a more eon'ipletc diselosureof the meehanism deseribed than has beendeemed neeessary tor the purposes of the present diselosure attention isdireeted.

to PatentNo. 82!),tt7l, issued to llaganke and Smith September 4, i906.

The shifting of the links 24 to effect the eonneetion and di eonncetionoi the keys and adding meehanism is aeeomplished by means of a yoke 26eomprising a shaft 27 having arms 28 eonneeted by a rod 2!) whieh rod isreeeived within longitudinal slots 30 in the links 24, see ligsv l and4. The shaft 27 is mounted to roek in braekets EH seeured to the underside of the eoverplate 4 of the earriagq 4. The yoke 2t} is shown Theand deseribed in the patent to [.aganke and Smith, above identified, andin the patented eonstruetion is equipped with a total key loeated abovethe earriage and movable to shift the yoke tor the purpose of swingingthe links 24 into or out of engagement with the keys 5.

ln earrying out my invention, the yoke 26 is utilized, but the total keyfor operating the same is eliminated, sinee there is no necessity forproviding manuallyoperated means for eausing the conneetion ol the keyswith the adding meehanism in addition to theautomat ie means whieh Iprovide for the aeeomplishment of this end; The means for rmto-mulirallyeo'n/no-l'iny Ihc keys with the register operating vim-han'is-in whenIla. printiny point of llm typeuua'tm' is presented [.0 I110 addingjirlll. This mechanism is normally inoperative, but is adapted to he setin operative eondition, and when soset, operates automatically to eausethe keys and adding meehanism to be eonneeted when the printing pointol' the maehine moves into the adding tield and to he automatieallydiseonneetml whenever the movement of the typewriter carriage presentsthe printing point outside of the adding lield. Substantially midway ofthe eover-plate 4 adjaeent to the front side thereof depends a braeket32 to one side of whieh is iulerumed, as indieated at. 33, a yokeoperating lever 144, see partieularly Figs. 6, l2 and lit. The front end35 ot' the lever 34 is biiureated, as shown in Fig. (l, to engage therod 25) of the yoke 24;, whieli yoke normally oeeupics the positionshown in Fig. l2 with the liiiks 24 swung baek out of engagement withthe key stems.

That portion of the levcriA lying in advanee of its t'ulerum isi'tlt'llCd to avoid interfere-nee with the shaft 27 of the yoke when thelever is swung, and the 'rear end of the lever is bifureated to formupper and lower arms 36 and 37, the latter being detleeted laterally tothe right, in order to present the arms in different vertieal planes..On the left hand t'aeeoi theleverZM is mounted what may he termed anabutment "plate 38 sli-dable longitudinally of the leverand gnidedinsueh movement by a headed stud 3t) projeeting from the lever at a pointabove and somewhat in advaneeof the fulerum ot' the lever and engagingan open-ended slot 40 in the plate 38. A t its rear end the abutmentplate 38 is provided with an abutment having the form of a roller 4Textended laterally from the plate and disposed be- .tween the arms 36and 37 of the lever 34, see l ig. t2.

It may be' stated at this point that. the abutment 4| normally oeeupiesan inoperative position, o-wit. that shown in Fig. l2, but is adapted tobe set in the operative position shown in Fig. [3 by means of settingmeehanism whieh shifts the abutment plate 38 to move the abutment- 4lbark to the rear end of the lever 34 where the abutment may be engagedby operating meehanism whieh, through the medium of the abutment, swingsthe lever 35 to shift the links 24 into engagement with the key stems aswill be more fully deseribed. I

The set! ing meehanism wln reby the abutment plate 38 is shiftedeomprises a setting lever 42 lulerumed intermediate of its ends, asindie-ated at 43, on the under side of the plate 4 and having an angularslotted end 44 whieh engages a pin 45 extended laterally from theabutment plate 58 in substantially the horizontal plane of the fulcrum33 of the lever 34, see Fig. 12.

The opposite end of the setting lever- 42 is connected to aslide 46located adjacent to one'end of the cover-plate 4 at the under sidethereof and having a projection 47 extended through slot 48 in the plate4 and secured to one edge of an indicator plate 49 having a key orfinger-piece 50 by means of which the slide 46 is shifted forward orback to swing'the lever 42 and thus shift the fulcrum plate 38 into orout of its set or operative position? The indicator plate 49 is alsoprovided with an opening 51 through which suitable subjacent indicationsare alternately visible, according as the abutment is set or unset. Forinstance, in Fig. 10 a second or bottom indicator plate 52 is providedwith two indi cations, to-wit, thewords total and add so located that inone position v of the upper plate 49 the word total will be exhibited atthe opening 51,

.while the word add will be obscured by the plate,

Whereas in the other position of the plate 59 the word ited.

. total may be printed in the addingfield, since the .Lsreached. Theslide 46 is guided by a bracket 53 secured to the under side of theplate 4, as shown in Fig. 1], and in order to yieldingly retain theslide in either position to which it is moved, said slide is provided inits under side with depressions 54 which are presented alternately inengagement with a yielding detent 55 mounted in the bracket 53. A headedscrew 56, also carried by the plate 4, assists'in guiding the slide. s

The mechanism operated by the movement of the carriage to swing thelever 34 and thus swing the yoke 26'to connect the keys and addingmechanism inclrides a cam'plate 57 extended across the front ofthecoinputing device casing, as shown in Fig. 9, and having its endsoppositely beveled. Arranged to co-act with the cam-platc 57 is an arm58 swung from a stud '59 projecting from the back wall of the carriagecasing,

see Figs. 2 and 5. The arm 61 is provided at its free end with alaterally disposcdlug 63 through which is screwed from the under sidethereof a contact screw 64 the upper end of which supports the arm 58.The spring 62 retains the lever 61 and the arm 58 in such position thatthe lug on said arm will engage the end of thc'platc 57 as the carriageadvances and this causes the arm 58 to be depressed by said plate as thecarriage continues to advance. This depression of the arm 58 will causecorresponding movement of the lever 61, the right hand end 65 of whichis bifurcated to engage the re ar end of what may be termed theintermediate lever 66 fulcrumed in a bracket 67 secured to the back wallof the casing 4. The front end of the intermediate lever 66 underliesthe abutment 41 in the operative or set position of the latter;Therefore when lever 34.

the front end of the intcrmediate leverctlfi isdepressed by the camplate57 through themedium of the arm 58 and the lever 61, the rear end 'ofthe lever 66 will be elevated. As the front end of the'lever isengagedwith the abutment 41, this movement ofthe l'ever66 will swing theyoke-operating Iever -34 from the 'position shown in Fig. 12 to thatshown in Fig. 13, thus causing the yoke 26 to be swung forwardly toswing the links of the computing device operating connections intoengagement with the stems ofthe numeral keys. The numeral keys 5 of thetypewriter will then remain in operative connection with the addingmechanism as long as the printing point of thetypewriter remainsopposite the adding field. As soonas the ,priuting'point moves out ofthe adding field, the plate 60 of the lever 58 having reached the end ofthe cain-' plate 57, will pass out from under the latter. The

. spring 62 will then immediately retract the lovers 61 and 66 and thearm 58 to normal position and will permit the retraction of the yoke 26,the lever 34 and-the links 24 to automatically disconnect the keys fromthe adding mechanism. 'This retraction of the yoke 26 may be effected inany suitable manner, but by preference, a yoke retracting spring 68 isconnected at one end to an'arm 69 on the shaft 27 and at'its oppositeend to a fixed part, as for instance, the bracket 53,

see Figs. 3 4 and 11. When the carriage is rctracted,,

the lug 60 of the arm 58 will engage the end of the camplate 57, butinstead of being depressed by the latter, will ride idly thereovcragainst the resistance of a spring 70 carried by the lever 61 andbearing upon the arni 58 and serving to compel the arm to rise from theupper end of the screw 64 as soon 'as the lug 60 has been retractedbeyond the plate 57.

Attention is now directed to the fact that in the normal rinset orinoperative position of thoabutment-plate 38, the'levcr 34 is not onlyinoperative by the lever66, but is also locked against such accidentalmovement as might result in the accidental connection of the keys,

and that when said plate is shifted to its 'operativc or.

set position, the lever 34 is released or unlocked, so that it may beoperated to swing the yoke and cause the I arcuate path, since as saidpin is fixed to the abutment-' plate, it is carried by and necessarilymoves with the Such arcuate movement of the pin ,45 is prevented,howcvcr,-by the engagement of said pinwith the setting lever 42, andtherefore said setting lever 42, by its cooperation with the pin 45,serves to lock the lever 34 against material accidental movement. Whenthe ah'uUncut-plate 38 is shifted, however, from the position shown inFig. 12 to that shown in Fig. 13, it not only sets the abutment 41 inposition to be engaged by the lever 66, but also moves the pin 45 to aposition substantially in line with the fulcrum 33 of the lever 34, sothat, when the lever 34 is operated, the pin 45 merely rotates partiallywithin the slot of the y I setting lover. .-\s the scllmg'lcvcr opposesno resistance to this rotary movement of the pin, it follows that thepin will present no resistance to the operation of the lever 34.

in order that the language of the claims may be better understood, itmay be observed that the links 2 1 constitute normally inoperativenumbers of the keyoperatcd actuating mechanism for the computing device;that the yoke 2t; and the lever 34 constitute means for moving saidmember into operatiVeposition; that the levers (it, the arm 58, and thecam 59 constitute mechanism operated automatically or by the movement ofthe carriage, and that the movable abut these arrangements which havepreceded it, the indicator indicates whether or not the kcys will beautomatically connected with the adding mechanism when the adding fieldis reached, instead of indicating whether or notthe keys are inconnected or disconnected condition. in other words, the indicatormerely indicates whether the automatic key connecting mechanism set forsubsequent action or not, and the operator is thus advised whether thedigit to be subsequently printed in the adding lield will bcaccumnlatedin the register without further manual manipulation of the mechanismcontrolling the connection between the keys and the register.

it is thought that from the foregoing, the construction and operation ofthe described key coma-cling mechanism will be fully comprehended, butwhile the present embodiment of the invention is thought at this time tobe preferable, I wish to be distinctlyundcrstood as reserving the rightto effect such changes, modifications and variations of the. illustratedstrucl are as may come fairly within the scope of the protection prayed.
